Synonym: ramus communicans cum nervo glossopharyngeo, ramus communicans nervi glossopharyngei cum ramo auriculari nervi vagalis. (05 Mar 2000) |
| posterior auricular artery | <anatomy, artery> Origin: posterior aspect of external carotid just above the digastric muscle; course: ascends first between parotid gland and styloid process then between cartilage of auricle and the mastoid process; branches: muscular (digastric, stylohyoid and sternocleidomastoid), glandular (parotid), stylomastoid artery, occipital and auricular; anastomoses: anterior tympanic artery (via the stylomastoid artery) and occipital artery.
